In the present investigation efforts have been made to synthesis polyvinyl pyridine (PvPy) /C60 conjugates through 2, 2-azobisisobutyronitrile (AIBN) initiated insitu polymerization of PvPy in scCO2.The process of synthesis was monitored under different reaction conditions ranging 1200-1800psi, 60-90 oC over 6 hours. The progress of polymerization was monitored rheoviscometrically. The concentration of PvPy and AIBN ranging 6.95-20.85*10-3 and 304.50-931.50 *10-3 afforded PvPy/C60 conjugates in the yield (%) ranging 10.30-48.8. Selected PvPy/C60 conjugates were characterized through UV-VIS spectra, scanning electron microscopy, gel permeation chromatography and solution rheoviscometery.
